Yes and no. The connections you made sound correct. But the F terminal of the generator does not ground through the fuse. You are supplying voltage from the switch terminal to the lights through the fuse. With a voltage regulator, there is no connection from the field terminal to the switch any more. The regulator makes it unnecessary as it now controls the charge rate. The fuse, by the way, was never a part of the field circuit. Even with the cut-out.

BigdogIf you can't fix it with a hammer, you've got an electrical problem.
